I was shocked when I saw I had a blue name to choose lol. Over a year and a half I somehow spent $1k. But I don't regret it at all. When I enjoy a game, I love giving back to those who created the game and those who keep it going. I dont know if donator pack sales go toward paying salaries or if it's just to keep server(s) running etc., but I'm happy to give back in that way.
I used my donator packs to help my faction, help new players, and I also used a vast majority of them to get both biz stocks I needed so I could run my biz.
I've put money into app games, laptop games, real life games (not gambling). I put money into collections, buying experiences, souvenirs, etc. I believe if someone gets pure enjoyment from things, there's no harm in using money to get memories or to show appreciation or to do a little better in a game, or what-have-you. Some look crosseyed at those who pay money for things but if you're sincerely enjoying an experience and decide to utilize money to add to the experience or show gratitude, where's the harm?
